Edge Cutter Top Feed 4-Thread Overlocker

Key Features:


There is an LCD display on the control panel, which features new functions such as automatic sewing, photocells, and the chaincutter.

Three Sewing Modes

There are three sewing modes: Automatic, Semi-Automatic, and Manual. The automatic mode works through sensors without the use of the pedal. The semi-automatic mode works with the automatic presser foot lifer and automatic chaincutter. The manual mode works by the user selecting the relevant aids from the control panel. This means the machine can be adjusted to suit any operator's needs.


The photocells on the machine allow you to start and finish the seam automatically, as well as activate the chaincutter and the foot lifter.

Automatic Electric Chaincutter

Thanks to the photocells, the electronic presser foot lifer and chaincutter are automatic at the end of the seam.

Optimised Feeding Structure

Fabric feeding on this machine is synchronised between the top feet and the feed dogs, meaning both thinner and thicker materials can be fed through and sewn evenly.

Optimised Needle Bar Structure

Fully enclosed needle bar construction and DLC (diamond like carbon) machining on the needle bar surface.

LED Light

Adjustable brightness on the light of the machine guarantees precision threading without straining the eyes.

Direct Drive Motor

This machine comes with an integrated, energy-saving motor, meaning assembly time on the machine is at a minimum.
